Answer 2

It seems like you've provided an expression with variables, but there might be some confusion or missing information. The expression you've given is:

Y/n - 2 + z/2 - n = ?

However, the denominator on the right side of the equation is represented as a question mark (?), which is unclear. Could you please provide more context or clarify the equation so that I can help you solve it or provide more information?
